Hi all,
... today I've tested a simpler methode for making PCB's than milling the outlines.
First I've coated some copper-clad PCB's with black paint ...
... then engraved the outlines with a diodelaser with around 2Watts of 975nm-IR-light on a spot of 0.15mm instead of milling them:

... mixed some hydrochloric acid with hydrogen peroxide and water and etched the freed copper complete away in maybe 40 seconds!:

... last removed the paint with acetone:
